I am not getting the usual turn the machine on “Camera Dance.”
It is much shorter in time and fewer moves which might be the result of a software upgrade?
I have some overhead fluorescent lights but with a cover over the lid no change.
Software updates are fully downloaded (even while printing if it doesn’t complete immediately following power-on) then checked before applying, which is then what you experience as a power cycle - the machine turns off briefly, then back on.
What you experienced was not a part of an upgrade cycle. Did it come back to life as normal?
